Bosch Logixx SMV69T10GB/26

Hi,

I have a Bosch Logixx dishwasher that has developed a fault that when switched on, two warning LEDs flash in unison – the one beside the tap icon and the one beside the rinse aid icon. The machine will no longer enter any cycles due to this error at startup. There is no accompanying ‘E’ error, just the two flashing LEDs.
The only other symptom is one small ‘click’ sound from the User Display PCB unit housed in the door. It clicks once at the same time the lights start to flash.

I have spoken to Bosch and they were unable to find any information on this error. There was one post on this site with the same problem, but called an engineer – the final resolution was not posted.

I suspect it is either the User Display PCB housed in the door at the top right or the main board bottom left of the machine.

Please could any body advise as to which PCB it is?

Many thanks

Tony
